Recently I have been using polyurethane resins for sculpting and casting projects and noticed an interesting term on all of my materials: Pot life. This is something that you see in all kinds of applications from epoxies, silicone, sealants, and building materials. A cursory definition of the term indicated that it was the working life of the material – the cutoff time when you can no longer make adjustments or clean up your projects. However, I found that the material was still very workable beyond the pot life time – in fact for some applications it even worked better.
